Subject: [PATCH] usb: gadget: fix error handling
Date: Thu, 7 Jan 2016 18:30:37 +0530 [thread overview]
Message-ID: <1452171637-25143-1-git-send-email-sudipm.mukherjee@gmail.com> (raw)
We are doing PTR_ERR() of NULL, and that will actually make ret = 0.
So incase of both error and success we are actually returning the
success code.
